Question

Solve :- (2x+3)^2=16. ​

Answer 1

Answer:

Solution :-

★ (2x + 3)² = 16

➞ (2x + 3)² - 16 = 0

➞ (2x + 3)² - (4)² = 0

➞ (2x + 3 + 4) (2x +3 - 4) = 0

➞ (2x + 7) (2x - 1) = 0

➞ (2x + 7) = 0

➞ 2x + 7 = 0

➞ 2x = - 7

➞ x = - 7/2

Either,

➞ (2x - 1) = 0

➞ 2x - 1 = 0

➞ 2x = 1

➞ x = 1/2

∴ The answer of this question is

- 7/2, 1/2
